I've been using Nero for a year or so and BackItUp seemed to work OK with CDRW's. Now I have a Toshiba SD-R5272 which can burn both CDs and DVDs. But while BackItUp seems to handle multidisks for CDRW, it doesn't seem to handle multidisks for DVD. For example, for a 2-disk DVDRW backup, the second (last) disk has the expected nbi file, txt files, plus directories with nco files. Actually these files are *.nc_ due to 8.3 file names I guess. But during a restore when BackItUp directs me to use the first disk, it turns out that the txt files are empty which prevents BackItUp from using it as a source disk.
I attempted to do a simple multidisk BackItUp using CDRW and it allowed me to use the first disk during a restore since its NB.txt file had the proper info. So it would appear to me that BackupItUp will not work with multidisk DVD backups and restores.
I just installed the lastest version of BackItUp (1.2.0.33) and it works the same way that the earlier version did by not working with DVDs. Just wondering what others might have run into.
